Abstract

The invention provides a reflection module and a periscopic camera. The reflection module comprises a shell, a base, a prism support, a prism, a first rotating shaft rotationally connected with the shell and the base, a second rotating shaft rotationally connected with the base and the prism support, a first driving assembly driving the base to rotate around the first rotating shaft, and a seconddriving assembly driving the prism support to rotate around the second rotating shaft. The first driving assembly comprises a first coil, fixed relative to the shell, and first magnetic steel fixed tothe base. The reflection module further comprises a concentrating flux plate arranged on the side, away from the first magnetic steel, of the first coil and fixed relative to the shell, and return magnetic steel arranged on the side, away from the first coil, of the first magnetic steel and fixed to the prism support. A restoring force for driving the base to rotate and reset is formed between the first magnetic steel and the concentrating flux plate, and a driving force for driving the prism support to rotate and reset is formed between the first magnetic steel and the restoring magnetic steel.

Description

technical field [0001] The invention relates to the field of periscope camera, in particular to a reflection module and a periscope camera adopting the reflection module. Background technique [0002] The main function of OIS (optical image stabilization, optical image stabilization) is to adjust the field of view of the camera to facilitate compensation for user hand shake. OIS is mainly achieved through "lens shift", that is, when the lens is moved or the camera is tilted, the lens and image sensor will be tilted together. At present, the industry uses reflective modules to achieve better optical image stabilization effects. [0003] The reflective module in the related art includes a base with a storage space, a base and a prism bracket located in the storage space, a prism fixed on the prism bracket, a first rotating shaft that rotatably connects the base and the base, and a rotatable connection between the base and the prism The second rotating shaft of the support, t...
